Mathematica Notebooks
These Mathematica notebooks run in the cloud, or can be downloaded to run with desktop Mathematica or the free Wolfram Player.
01
Usually updated weekly this notebook of visuals summarises the fuel mix used to generate our electricity and calculates a daily rank for each fuel type.
02
To see a linear (regular) increase in shape size, there needs to be a larger difference (β) between larger shapes than smaller ones. This notebook lets you adjust β; research suggests β = 0.7 is close to achieving this.
03
Perception of size and length is complex, the Ponzo illusion demonstrates this. One explanation is that we see the world in perspective 3D and judge 2D size and length relative to estimated 3D world distance, not simply by the projected size on the retina.
04
How do we know if a viewer can see our visualization on their display? Fourier analysis can help understanding image content via its frequency content and knowing screen size we can calculate potential visiblity.
